SO.LRT computes the likelihood ratio test statistic for stochastic
ordering against equality assuming marginal compatibility for both
alternatives. Note that this statistic does not have a
\(\chi^2\) distribution, so the p-value computation is not
straightforward. The SO.trend.test function implements a
permutation-based evaluation of the p-value for the likelihood-ratio test.
Usage
SO.LRT(cbdata, control = soControl())
Value
The value of the likelihood ratio test statistic is returned with two
attributes:
ll0
the log-likelihood under \(H_0\) (equality)
ll1
the log-likelihood under \(H_a\) (stochastic order)
Arguments
cbdata
a CBData object
control
an optional list of control settings, usually a call to
soControl. See there for the names of the settable control
values and their effect.
